Application filed January 3, 1921. Serial No. 434,665.

i 10 all w hom t may concern Be it known that l, SAMUEL citizen of the United States, and residingat Chicago, in the county of Cook and State of illinois, have invented certain new and useful improvements in Automobile Jacks, of which the following is a specification.

This invention relates to jacks or lifting devices or for vehicles; such as automobiles or the like and more particularly to a device of this character, which is adapted to elevate and support the entire car.

The objects of this invention are to provide an improved jack, which is adapted to raise automobiles off from the ground and support it in raised position;

To provide a device of this character whereby the vehicle may be lifted by the movement of a single lever;

And in general to provide such an improved constructionv as will appear more fully from the following description.

.ln the accompanying drawings showing a preferred form of my invention;

Figure 1 is a side view with an automobile shown in dotted lines, in raised posit-ion;

Figure 2 is a plan view;

Figure 3 is a detail on an enlarged scale illustrating the lifting mechanism;

Figure l is a cross sectional view of the parts shown in Figure 3; and,

Figure 5 is a detail showing one of the adjustable rails in lowered position.

As shown in these drawings, the jack has a base or frame 6 which may be made in any7 suitable manner, but preferably consists of side bars 7 and end bars or cross pieces 8. A vertically movable frame 9 is mounted above the base 6 and is guided in this movement by means of pins 10, which are secured in cross pieces 11 in the base 6 and engage with holes 12 in cross pieces 13 of the frame 9.

The frame 9 is raised by means of suitable mechanism whereby suicient leverage is provided. so that it can ordinarily be lifted by one person. In the present instance I provide links 14 which are pivoted on shafts 15 in the base 6. These links have curved shoulders or cams 16, which engage with the flanges 17 of t-he side bars of the frame 9.

Thellinks on one side of the jack are connected by a bar 18 and the links on the opposite side are connected by a bar 19. These bars are bent inwardly as shown in J. Rien, a

Figure 2 and are connected to a draw bar 2O by means of va pivot 21. The draw bar 2O has a hook 21 at one endfor engagement with a pin 22 in a lever 23, which leverris.

pivoted at 24- to the base 6. j

In some instances the structure thus described would be sutlicient if the parts were madeto lit a particular type'or make ofcar. However; l prefer to have vertically adjusted rails or beams 25, which engage directly with the axles of the car. These rails are hinged at their end to short adjustable posts 26 by means of hingesl 27. The posts are hinged to the frame 9 by means of hinges 28, the arrangement being such that the rails may be lowered by moving them in one direction as indicated in Figure 5.

My improved ack or lifting apparatus is intended to remain in substantially fixed position in the garage and the car is driven over the same preparatory to being elevated. It will be noted that the lever 23 may be released from the hook 21 and lowered so that the car .can be driven on from either direction. The rails 25 will ordinarily be in lowered position when the car is driven over the jack. They are then swung upwardly as shown in Figure 1 preparatory for lifting the car. The lever 23 is then swung outwardly which causes the draw bar 20 to pull on the barsl8 and 19 and swing the links 14 up to vertical position as shown in Figures 3 and 1. The shoulder or cams 16 raise the frame 9 and this movement causes the rails 25 to engage with the axles of the car and raise it to elevated position.

Any suitable locking mechanism may be used for locking the frame 9 in raised position so that the car can not be readily removed fr'om the jack. F'or instance this may be done by means of a hasp or arm 29, which is hinged at 30 to the cross piece 11 and is adapted to engage with a staple 31, which may be provided with a pad lock 32.

It is well understood that it is desirable to raise an automobile, when standing for any considerable length of time, so that it will not be supported by the tires. My invention provides means whereby this may be readily done, as well as means for protecting the car against being stolen. Furthermore the car may be held in raised position so that the lower parts will be more accessible when `work is to be done underneath the car.`

Having thus described my invention what l claim and desire to secure by Letters Patent is;

l. A jack for vehicles comprising la ibase, a single vertically movable frame mounted on said base, manually operable means for raising said frame With the vehicles thereon, and vertically adjustable members carried by the frame, and adapted to engage With the vehicle t0 be raised.

2. In a jack, the combination of al rectangular base, a frame mounted on y'said base,

verticaly guidesl for saidv frame, elevating mechanism for raising the frame, 4and adjustable rails carried 'by said -frame and adapted to 'engage'with the front and rear axle members of an automobile.

3. In the jack for vehicles, the combination fof a rectangularbase of approximately the length `of the vehicle and adapted to lit between the vehicle Wheels, a single vertically movable frame mountedy on said base,

links p'ivoted to saidbase and yengaging with *y said frame' for raising the same, bars connecting said links, a draw bar plvotally connected to said bars, a lever pivoted to said base and engaging with said draw bar, and.

vertically adjustableL members carried vioy said frame and adapted to engage With the vehicle. f

4. The combination of a rectangular base 'hinged to said posts and adapted `to engage with the vehicle, substantially as described,
